Description

n-Palmitoyl-Tyrosine Phosphoric Acid (Ammonium Salt) is a specialized, high-purity phospholipid derivative designed for advanced formulation and research applications. This compound is valued for its unique amphiphilic structure, which combines a long-chain fatty acid with a phosphorylated tyrosine moiety, enabling precise control over surface activity and biological interactions. It is primarily utilized by researchers and product developers in the pharmaceutical, cosmetic, and advanced material science sectors seeking innovative lipid-based delivery systems and bioactive intermediates.

Application

• As a key phospholipid component in the development of novel liposomal and nanoparticle drug delivery systems.
• As a functional excipient or bioactive intermediate in advanced dermal and transdermal pharmaceutical formulations.
• In high-end cosmetic products as a skin-identical lipid for enhancing barrier function and active ingredient delivery.
• For biochemical research involving signal transduction pathways and lipid-protein interactions.
• As a specialty surfactant or emulsifier in the formulation of complex, multi-phase systems.
• In the synthesis of more complex, target-specific phospholipid conjugates for diagnostic or therapeutic applications.
